GRM319R71H473KA01D

The GRM319R71H473KA01D is a multilayer ceramic capacitor (MLCC) manufactured by Murata, one of the world's leading producers of passive electronic components. This compact surface-mount capacitor is designed for high-reliability applications where stable performance and consistent electrical characteristics are essential across varying operating conditions. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, used to filter, couple, and bypass signals in circuit designs. The GRM319R series represents Murata's established line of general-purpose MLCCs, positioned for mainstream industrial and consumer applications requiring dependable performance without exotic specifications. These capacitors are constructed from alternating layers of ceramic dielectric material and metallic electrodes, which are then sintered together to create a monolithic structure. This construction method allows manufacturers to achieve high capacitance values in extremely compact packages, making MLCCs ideal for space-constrained designs. The part number structure indicates specific electrical and package characteristics. The GRM319 designation tells engineers this is a compact surface-mount component in the 1206 package size (3.2mm × 2.5mm × 2.5mm), which has become the de facto standard for many applications balancing size constraints with handling ease in automated assembly environments. This package size is substantially smaller than through-hole alternatives, enabling higher component density on printed circuit boards while remaining large enough for reliable hand soldering and rework when necessary. Engineers typically specify this exact part number when designing circuits that require a proven, readily-available capacitor with established long-term reliability history. The Murata GRM319 series benefits from decades of production experience and integration into countless successful products across industrial automation, telecommunications infrastructure, medical devices, and consumer electronics. This heritage translates to predictable performance, consistent quality from lot to lot, and simplified procurement compared to newer or less-established alternatives. The ceramic dielectric formulation used in Murata's mainstream MLCC lines generally provides stable capacitance across temperature ranges typical for industrial equipment and consumer devices. These capacitors excel in filtering high-frequency noise, decoupling power supplies close to integrated circuit pins, and AC coupling applications where their compact size and low equivalent series resistance offer clear advantages over film or electrolytic alternatives. For engineers evaluating this part, key considerations include compatibility with lead-free, RoHS-compliant manufacturing processes, ease of integration into existing supply chains, and the extensive application notes and technical resources available from Murata. The standardized 1206 package also ensures broad availability from multiple distributors, reducing single-source risk in production environments.
